Many Don't Use Their Real Name on the Internet, Reveals Social Networking Survey

Chubb Hosts Risk Management Innovation Event Online Through May 14

WARREN,NJ,April 29, 2010– Only half (51%) of the people surveyed always use their real name on social networking sites. Eighteen percent said they
always use a nickname. A third (31%) said they sometimes use their real name and sometimes use a nickname to identify themselves
on social networking sites, according to a survey of 1,040 Americans sponsored by the Chubb Group of Insurance Companies.

“Twitter, Facebook and Foursquare have created new social media risks and an environment where many people don’t know who
they are talking to online. They don’t realize who can see their location, creating many exposures for individuals and companies,”
according to Kenneth Goldstein, worldwide media liability manager at Chubb.

Does everyone know where you are?

Two-thirds (66%) of respondents said they would not use mobile technology that shows people on social networking sites where
they are located.

“Although this lets your friends know where to find you, it also alerts criminals of your whereabouts, including when to burglarize
your empty home,” said Goldstein.

Negative experiences?

Nearly 20% of respondents said they have shared a negative product or service experience with others on Facebook, YouTube
or other social networking sites.

Social networking at work?

Almost two-thirds (64%) of respondents said their company had no policy for talking about the company on social networking
sites. Of the 36% who said their company had a policy, 18% said they were encouraged to talk about the company and 18% said
they were prohibited from talking about the company on social networking sites.

Chubb launched an interactive, worldwide discussion on social media risk management earlier this week at the Risk & Insurance
Management Society annual conference in
Boston. The event, which is accessible on PCs, laptops and mobile devices, runs through May 14. To register, go to https://chubbsocialmedia.imaginatik.com. For more information, visit http://bit.ly/b8XvyL.

The online survey was conducted by Opinion Research Corp. in April 2010.
